Several C,X-chelate complexes of iron were generated via standard metathetical procedures. Treatment of FeCl2 and LnFeCl2 (L = Me2IPr, n = 1; PMe3, n = 2) with anionic equivalents o-LiCH2C6H4NMe2, o-LiCH2C6H4PPh2, and LiCH2PMe2 led to the preparation of [Fe(o-CH2C6H4NMe2)]2(κ-μ-CH2,N-o-CH2C6H4NMe2)2 (1, X-ray), [fac-Fe(κ-C,P-o-CH2C6H4PPh2)3][Li(TMEDA)2] (2, X-ray), (Me2IPr)Fe(CH2C6H4-o-NMe2)2 (3-C
通过标准复分解方法生成了几种铁的C,X螯合物。用阴离子当量o-LiCH 2 C 6 H 4 NMe 2,o- LiCH 2 C 6 H 4 PPh处理FeCl 2和L n FeCl 2(L = Me 2 IPr,n = 1; PMe 3,n = 2)2,和的LiCH 2 PME 2为首的制备的[Fe(O-CH 2 C ^ 6 ħ 4 NME 2)] 2(κ-μ-CH 2,No-CH 2 C 6 H 4 NMe 2)2(1,X射线),[ fac -Fe(κ-C,Po-CH 2 C 6 H 4 PPh 2)3 ] [Li(TMEDA)2 ] (2,X射线),(Me 2 IPr)Fe(CH 2 C 6 H 4 -o-NMe 2)2(3 -C,N),[(Me 2 IPr)2 Fe](μ-κ- C,P-CH 2 PMe 2)2 [Fe(κ-C,P-CH2 PMe 2)2 ](4,X射线)和(PMe 3)2
